yes they are. I guess I side with the majority. My son recently had a brain aneurysm and was fixed up at the Barrow'
s clinic in Phoenix, AZ (he is fine now). During the process they use dye and X-rays to check on the progress of stopping the leak. The doctor's post op instructions to us were for him to specifically avoid any X-rays that we could - his example was dental X-rays. When we asked about the body scanner he was very emphatic that it should be avoided - he regarded it as much more problematic than the dental exam. He stated that he would be going for the grope option, instead of the nude photo.
